Nicor Gas claims that all customers recorded heard a ‘warning’ before being recorded, and ‘consented’ by remaining on the line after the warning was given. But under the law, any consent only gave Nicor Gas a right to record, not to divulge or use the recordings. Any ‘consent’ they got from customers that permitted them to record was for the limited purpose of internal quality assurance – not for divulgence to outside parties, and certainly not for use in public court proceedings
— Adam Levitt, a lawyer with Grant & Eisenhofer, in a class action filed against Nicor Gas, a natural gas distributor in northern Illinois. Nicor had a plan. They were so proud of using their recordings of customers in their defense. Too bad Illinois has an Eavesdropping Act that prohibits that. D’oh!
